Part of the official G20 event series, the U20 Mayoral Summit Exhibition was inaugurated by Hon'ble Chief Minister Shri Bhupendra Patel across 1,700 sq. mtr. of curated exhibition space. Kamnath designed and delivered an immersive experience showcasing the challenges and solutions shaping the summit's key priorities, attended by Mayors of 20 countries alongside VIPs and dignitaries from across Indian cities.

The exhibition combined thematic storytelling with striking visual design. It featured heritage-inspired installations echoing India's architectural legacy, bold and color-coded solution walls mapping urban innovation, and immersive black-and-white corridors tracing the evolution of Indian cities through time. Delivered end-to-end across event management, branding, and hospitality, the exhibition gave global delegates a tangible, walk-through narrative of India's urban future.
